I think they said around 50, though that was an estimate early on and it may be very different now. And that's actual options. 10 options with 10 settings is still 10 options, not 100. So 50 or so different options, each with 2 to X choices.
I have high hopes anyway that it'll turn out to be a fantastic update. It's just that, you know, the more variety, the better. 
There are already well over 100 unique options though, admittedly, some of them are already-existing options that are mixed in. But even some of those have been reworked for better customization. For example, Rage mode was baked into whatever difficulty you chose. But now rage chance is its own unique option that can be adjusted independently of other options. I've found that with the ability to combo different individual options even many of the options we already have in the game feel new and more interesting than they did before.
Neither Richard or Joel Huenink consider them investors. They were just someone to scam or let down bigly. Not entirely sure which.
